Discovery

KELT-10b was discovered by a group of scientists at the SAAO using the KELT-South telescope. The light curves and parameters of the system were observed, and it iss predicted that due to the host's activity and evolution state along the HR Diagram, the planet is bloated. KELT-10b is part of a group of exoplanets that will be observed by the ESA mission ARIEL.
